Completely agree with this. Did you work at Google?
Let me explain this a little more in concrete terms: are you passionate about what you do? Do you have pride in your work and want to create great, valuable (to users of course, but also profitable) software? You will probably dislike working at Google.
First, if you’re an engineer, you’re basically not going to be empowered to make important product-level decisions on anything people care about until you’re a well-established L6 or L7. Even then, you’re more of a voice in the room with the Product Managers and Directors/VPs (you might have 5 directors+ VPs who also are on your product) and business stakeholders for the little chunk you’re actually responsible for. Google is extremely hierarchical, not just in terms or a deep org chart but in empowerment, for a variety of reasons I won’t get into. Nobody will listen to you or care until you’re at this point, your ideas and suggestion will be treated like a child at the Thanksgiving kid’s table asking for a glass of wine.
Ok, so become a product manager. Well then you have to deal with the fact that you are amazingly constrained by things outside of your control, like the headcount and capacity of engineering teams who have to handle a bunch of internal migration bullshit, want to refactor or rewrite something for no business reason except because it’s easy coasting material, and handle requests from a dozen other PMs. You have to deal with a ton of bureaucracy and process bullshit just to get your product ideas turned into reality. You have no idea what’s easy and what’s hard because engineering at Google is different than at other companies (the “impossible” is just hard, but the “easy” is also hard). You’re not empowered to step in and code and design even if you can and want to. You are gonna spend a lot of time writing SQL and docs nobody cares about and still need to make it to a high “level” to matter.
Well what happens if you do get to that high level? Then you’re in charge of a million and one things and mostly doing performance management. You don’t have time to care about a product - you are the gatekeeper of it and can have strong opinions, but you simply do not have time to be passionate about it, because you have too many responsibilities and are too far removed from the actual work/product/users. You still have a deep management chain above you to contend with, you play political games for HC and need short term wins to secure it, you’re probably in a different stage of your life where your passion project is either career (not product) and/or family.
It’s still a great place to learn, the pay and benefits are still good, you still probably get to work on something cool. But your ambitions and passion will be crushed unless you can endure a decade+ of being a ~nobody. If you truly want to build something amazing you’ll have to go elsewhere.
